Best Mobos for Dual-Core Xeons (7000/7100)

Intel Ibm intel xeon dual-core 7140n 3.3...

Specs: Windows XP Pro
I have a pair of 3.33 dual core Xeons (7140N) that I'd like to use in a machine I'm building however I am having a very hard time finding an appropriate mobo for my needs. So far, all I've been able to locate are huge 4 CPU rack mount or EATX mobos which is NOT what I want.

What I'm looking for is an ATX mobo that'll take the two socket 604 CPUs.

From what I understand the 7100 series "Tulsa"processors were the next incarnation of the 7000 Paxville MP CPUs... If I were to put them in a mobo designed for the Paxville MP cpus would they work? I'd rather not have to buy an entire mobo to figure out.

The differences that I can see between the two are that the Tulsa processors are 65 nm and the older ones are 90 nm, the newer 7100 CPUs have an L3 cache, and older cpus need an 800 FSB while the newer ones require 667.

Any help would be appreciated. This has a been a horrible headache. At this point I just want to make it work. If I lose some performance in the process I don't care as long as the machine boots and whatever mobo I get uses what it can.

Also, I've done a lot of research on what mobos 'officially' support the CPUs (which aren't many), so now I'm treading into the realm of 'unofficially supprted' which obviously won't be on any spec sheets.

See newegg and other places for a server board. Intel used to make a board and still should be out there.

You may have no luck making a workstation, this is a server product. All that server stuff may cost more than the performance you'd get out of a newer processor. Remember, processor time is closely tied to ram speed in most tests. A cheap AMD Athlon II is running 1066MHz ram. That more than makes up for any processor cache issues in a lot of cases.

I mostly just want to know if the machine will boot by using that CPU in a mobo intended for dual core CPUs in the 7000 series.

Well pretty much if the chip can fit in the socket you have a good chance it will work.
